    摘要： An apparatus comprises a shaft, an end effector, an articulation joint, and an articulation drive assembly. The shaft has a longitudinal axis. The end effector is operable to staple tissue. The articulation joint couples the shaft with the end effector. The end effector is pivotable at the articulation joint to selectively deflect the end effector away from the longitudinal axis of the shaft. The articulation drive assembly is operable to pivot the end effector at the articulation joint. The articulation drive assembly comprises a first link and a second link. The first link is longitudinally translatable relative to the shaft assembly. The distal end of the first link is pivotably coupled with the proximal end of the second link. The distal end of the second link is pivotably coupled with the end effector. The articulation drive assembly articulates the end effector in response to longitudinal translation of the first link.

    摘要： A surgical instrument comprises a body, shaft, and end effector. The shaft couples the end effector and body together. The end effector comprises an anvil and lower jaw configured to receive a surgical staple cartridge. The anvil is configured to pivot toward and away from the staple cartridge and lower jaw. The shaft assembly comprises a knife member configured to longitudinally translate to thereby substantially simultaneously cut clamped tissue and staple the severed tissue. The end effector may comprise lockout features configure to prevent longitudinal translation of the knife member. The end effector or staple cartridge may comprise lockout bypass features configured to prevent lockout of the knife member. These lockout bypass features may operate to permit longitudinal translation of the knife member once or multiple times. The end effector may comprise features configured to ensure proper alignment of the anvil relative to the staple cartridge.

    摘要： A surgical circular stapler has a handle assembly, a shaft, a stapling assembly, a motor, a drive assembly, and a firing assembly. The shaft extends distally from the handle assembly. The stapling assembly is secured to a distal end of the shaft. Longitudinal translation of the firing assembly causes the stapling assembly to drive a plurality of staples in a circular array to secure two lumens of tissue together. The stapling assembly may further drive a blade to sever any excess tissue interior of the circular array of staples. The motor is operable to rotate the drive assembly to thereby translate the firing assembly. A resilient member biases the firing assembly proximally. Through cooperation between the firing assembly and the resilient member, the firing assembly is driven distally and proximally to complete a firing stroke in response to rotation of the drive assembly through a single revolution.
